Here are some of the card designs available, I can custominze your saying , but on these particular designs I can not change the "Happy Holidays or Season's Greetings".
These cards are available either vertical or horizontal.
Cards come in either a 4x6 or 5x7 size.
Here are some custom made designs that I have made , wording of course is always personalized to whatever you choose however these designs are not available in both orientations , only what it is shown as.
